It accepts connection credentials via an intuitive URL format supporting both plain SMTP and encrypted SMTPS connections, making configuration straightforward without complex parameter handling. Recipients can be specified as a single address, an array, or a comma-separated string, with support for CC and BCC fields for flexible distribution. The tool sends both plain text and HTML formatted emails, enabling rich content delivery including formatted newsletters, styled notifications, and branded communications. File attachments are supported through base64-encoded content with configurable MIME types for documents, images, and other media. Email priority levels allow marking messages as low, normal, or high importance for recipient mail client handling. The sender address can be explicitly set or automatically derived from the SMTP username, simplifying configuration for common use cases. This tool is optimized specifically for email delivery. For workflows requiring additional protocols such as FTP file transfers, SSH command execution, or MQTT messaging alongside email, use the Protocol Bridge tool which provides a unified interface across multiple network protocols. ### Agent Description Send emails via SMTP with HTML/text body, attachments, CC/BCC, and priority levels.

Format: `smtp://username:password@hostname:port` for STARTTLS (port 587) or `smtps://username:password@hostname:port` for SSL/TLS (port 465). | | `to` | array or string | Recipient email address(es). Accepts an array of strings, a single string, or a comma-separated string. | | `subject` | string | Email subject line. | | `body` | string | Email body content, plain text or HTML depending on `body_type`. | **Optional Fields:** | Field | Type | Default | Description | |-------|------|---------|-------------| | `from_email` | string | Username from `smtp_url` | Sender email address. Useful when sending from a different address than the one used for authentication. | | `body_type` | string | `"plain"` | Body format: `"plain"` for plain text, `"html"` for HTML content. | | `cc` | array | — | CC recipients. Array of email addresses. Visible to all recipients. | | `bcc` | array | — | BCC recipients. Array of email addresses. Hidden from other recipients. | | `attachments` | array | — | File attachments (max 25MB total). Each object requires `filename` (string) and `content` (base64-encoded string). Optional `content_type` (MIME type, defaults to `application/octet-stream`). | | `priority` | string | `"normal"` | Email priority: `"low"`, `"normal"`, or `"high"`. Sets the X-Priority header. | **Example — Send a plain text email:** ```json { "action": "send", "smtp_url": "smtp://user:app-password@smtp.gmail.com:587", "to": ["recipient@example.com"], "subject": "Monthly Status Update", "body": "Hello,\n\nHere is the monthly status update.\n\nBest regards,\nThe Team" } ``` **Example — Send an HTML email:** ```json { "action": "send", "smtp_url": "smtps://user:pass@smtp.example.com:465", "to": ["recipient@example.com"], "subject": "Welcome!", "body": "

Welcome!

Thank you for signing up.

", "body_type": "html" } ``` **Example — Send with CC, BCC, attachment, and high priority:** ```json { "action": "send", "smtp_url": "smtp://user:pass@mail.example.com:587", "to": ["recipient@example.com"], "cc": ["manager@example.com"], "bcc": ["archive@example.com"], "subject": "Q1 Report", "body": "Please find the quarterly report attached.", "priority": "high", "attachments": [ { "filename": "report.pdf", "content": "JVBERi0xLjQK...", "content_type": "application/pdf" } ] } ``` **Example — Multiple recipients with a custom sender:** ```json { "action": "send", "smtp_url": "smtp://auth-user:pass@mail.company.com:587", "to": ["alice@example.com", "bob@example.com"], "from_email": "noreply@company.com", "subject": "Team Announcement", "body": "

Please review the updated policy.

", "body_type": "html" } ``` ## Common Workflows 1. **Send a notification email** — Use the `send` action with plain text body to deliver a quick notification to one or more recipients. 2. **Send a formatted newsletter** — Set `body_type` to `"html"` and provide styled HTML content with images and links. 3. **Distribute a report with attachments** — Attach base64-encoded files (PDF, CSV, Excel) and send to recipients with CC for visibility. 4. **Confidential distribution** — Use `bcc` to send to multiple recipients without revealing other addresses. 5. **Urgent communication** — Set `priority` to `"high"` to flag the email as important in recipient email clients. ## Important Notes - **Gmail users**: You must use an App Password, not your regular account password. Generate one at https://myaccount.google.com/apppasswords. - **SMTP URL schemes**: Use `smtp://` for STARTTLS (port 587, recommended) or `smtps://` for direct SSL/TLS (port 465). - **Attachment size limit**: Total attachment size must not exceed 25MB. - **From address**: Some providers (like Gmail) enforce that the sender address matches the authenticated account. Use `from_email` only when your provider allows sending from an alias. - **Priority**: Use `"high"` priority sparingly to avoid emails being flagged as spam. - **Common MIME types for attachments**: `application/pdf`, `text/csv`, `application/vnd.openxmlformats-officedocument.spreadsheetml.sheet` (Excel), `image/png`, `image/jpeg`, `text/plain`. ### About The Developer - Vendor name: Apoth3osis - Website: apoth3osis.io We build tools that enable AI agents to excel in the mathematical realm.
